ABSTRACT

The squamous odontogenic tumor (SOT) is a rare, benign, locally infiltrative neoplasm of the jaws that appears to originate from the rests of Malassez, gingival surface epithelium or from remnants of the dental lamina. SOT was first described by Pullon et al. (1975). Since then there has been paucity in the number of reported cases, especially in the Indian subcontinent. The tumor is often asymptomatic, although it can present with symptoms of pain and tooth mobility. The characteristic radiographic appearance is that of a triangular-shaped unilocular radiolucency associated with the roots of erupted, vital teeth and has a predilection for the anterior maxilla and the posterior mandible. Histologically, the tumor is characterized by the formation of variably sized nests and cords of uniform, benign-appearing, squamous epithelium with occasional vacuolization and keratinization. We report a case of SOT occurring in a 58-year-old male in the anterior mandible with unusual localization and appearance.

    ABSTRACT: Squamous odontogenic tumors (SOTs) are benign, locally infiltrative neoplasms that localize to the periodontium. In total, <50 cases have been reported since the first description of SOTs in 1975. Although the exact etiology of SOTs is unknown, the tumors are considered to derive from the epithelial cell rests of Malassez. SOTs are characterized by radiological and clinical signs and symptoms, including pain with increased sensitivity in the affected area, bone expansion and increased tooth mobility. The present study describes the case of a patient that experienced numerous SOT recurrences and also discusses recommendations for treatment. A locally invasive mandibular SOT was identified in a Caucasian 41-year-old female patient. The treatment involved recommended conservative surgery, including local curettage. In addition, 49 cases published in the literature were reviewed to assess the treatment strategies. The present patient experienced two recurrences of the tumor during the 6-year follow-up period. Ultimately, the vitality of the adjacent teeth was compromised. An apicoectomy with a small amount of resection of the marginal bone was necessary. In >50% of the reported cases of SOT in the literature the adjacent teeth were extracted. The present case of SOT and the associated literature were also discussed. It was concluded that the treatment of choice appears to be a conservative surgical removal, but the successful management of SOTs often requires the removal of the adjacent teeth.
